摘要： A transceiver 400 is provided in an ultrawide bandwidth device, which includes an antenna 110, a transmitter circuit 145, and a receiver circuit 165. A transmitter amplifier 440 is provided between the antenna 110 and the transmitter circuit 145, and is configured to have an operational transmitter output impedance when the transceiver 400 is in a transmit mode and an isolation transmitter output impedance when the transceiver 400 is in a receive mode. A receiver amplifier 460 is provided between the antenna 110 and the receiver circuit 165, and is configured to have an operational receiver input impedance when the transceiver 400 is in a receive mode and an isolation receiver input impedance when the transceiver 400 is in a transmit mode. The isolation transmitter output impedance is greater than the operational receiver input impedance, and the isolation receiver input impedance is greater than the operational transmitter output impedance. Thus, a transmitter and receiver can be isolated without using a transmit/receive switch.

摘要： A display driver circuit (100) includes N scanning drivers (150) for driving a scanning set of display electrodes of a display panel (160) with a set of scanning signals (155), P information drivers (130) for driving an information set of display electrodes of the display panel (160) with a set of information signals (135), and a control section (120) having a first mode and a second mode. In the first mode the control section (120) controls the N scanning drivers (150) to generate N different scanning signals (155). In the second mode the control section controls the N scanning drivers (150) to generate a common scanning signal by S of the scanning drivers (156) and N-S different scanning signals by N-S drivers of the scanning drivers (157), wherein N, P and S are positive integers.
